Improved Collectors for Flotation of Bastnaesite (Journal

Apr 11, 2018Bastnaesite is an important mineral because of its abundance and rare earth content. Calcite and barite are the most common gangue minerals associated with bastnaesite. The importance of finding a suitable collector that can be selective against the gangue minerals without heated conditioning is critical to the advancement of the beneficiation

Synergistic adsorption of lanthanum ions and fatty acids

Rare earth elements (REE) are indispensable in our daily life but they naturally occur in minerals, which are generally difficult to concentrate by the froth flotation method. Considering the significant affinity of lanthanum ions for phosphate species as well as for carboxylate groups, the influence of a lanthanum salt (LaCl 3 ) on the adsorption of carboxylate species on

Abstract Flotation separation and recovery of rare earth minerals (REM) have returned to an important position due to the growing strategy demand for rare earth elements (REE). In this paper, the floatability of bastnaesite ((Ce,La)FCO3) was comparatively investigated by using three di/trialkyl phosphate collectors, di(2ethylhexyl) phosphate (DEHPA), dibutyl phosphate (DBP)

Froth Flotation

This greatly reduces the amount of acid and time that would be consumed to dissolve this feldspar and mica. In froth flotation it is very important to have a fresh, newly cracked surface. It is also just as important for the sample to be of the correct grain size (between ), otherwise the grains will either sink or float.

Recent Advances in the Separation of Rare Earth Elements

May 27, 2018Over the past decades, the need for rare earth elements (REEs) has increased substantially, mostly because these elements are used as valuable additives in advanced technologies. However, the difference in ionic radius between neighboring REEs is small, which renders an efficient sizedbased separation extremely challenging.
